We investigated the interaction between the oak wilt pathogen (Ceratocystis fagacearum) and propiconazole in lower stems and roots of Quercus rubra to better understand published reports of fungicide failure after 2 years. Propiconazole was infused into mature oaks in July 2004 and roots were inoculated with pathogen endoconidia 1.0 m from injection sites at ±2 weeks of fungicide treatment. Pathogen presence in wood samples was determined by isolation and fungicide concentrations measured using… CONTINUE READING
